The Rotating Bracelet Spin Shuttler (回転腕輪スピンシャトラ,Kaiten Udewa Supin Shatora?) is the main transformation device of the core AstroNauters. It is a bracelet with a black base over which lies a navy and star-spotter fidget spinner-shaped structure with a common center in which there is the AstroNauter's team symbol, and three edges in whose center there is a hole to insert a Trial Spinner. On the tip of each of the edges is a pulling trigger to activate the function if a Spinner is inserted in it.

Each of the edges has two specific functions: The first edge allows for Transformation (by inserting the core Spinners and pulling the trigger once) and Nauter Tool Summoning (by doing it twice). The second edge allows for Nauter Bot Arms Activation (by inserting a Bot Arms Spinner and pulling the trigger once) and Nauter Bot Arms Finisher (by pulling the trigger twice). The third edge allows for Voyager Calling (by inserting the core Spinners and pulling the trigger once) and Voyager Dashing (by pulling it twice).

To deactivate, the first edge needs to be taken off its Spinner and then pulling the Trigger. Otherwise, if the user is transformed and weakened too much, the system will close itself automatically.

The Trial Spinners (トライアルスピナー,Toraiaru Supinā?) are a set of fidget spinner-like devices that work as the medium of the AstroNauters to use their source of power in combat. There are a total of 50 Trial Spinners which were created during the Ordinal Trial and used to hold the energy and functioning of several objects and structures found in the Universe. After centuries, those that have been passed through generations or found are kept by the Oozora Alliance, and modified to enhance their abilities.

Their power is measured according to the amount of edges they possess, the edges being styled in a specific manner according to the Clan that created them. The Oozora Alliance classifies them that way: those with 3 edges are Average Powered; those with 4 edges are Greatly Powered; those with 5 edges are Ultimate Powered; those with 6 edges are Overpowered.

Currently only 16 Spinners are known and they all belong to the Average Powered category.

The Nauter Tool Holder Pac Bag (ナウター ツール ホルダー パック バッグ,Nautā Tsūru Horudā Pakku Baggu?) is a backpack-like structure that the AstroNauters carry in the back of their suits. It is a bland, white with red and blue accents bag that is joined with two silver suspenders, and has a black lever coming out on top of a shoulder. Most of it is however composed by the Nauter Tool which is the weapon of the AstroNauters. To "take it out" of the bag, the user holds onto the shoulder lever and pulls it out. This lever will become the central piece of the Tool. According to the rank of the user, there are different modes for it.

The Nauter Hishe (ナウター ヒシェ,Nautā Hishe?) is Mars Nauter's primary tool and weapon. It is a bow.

The General Use Equipment Spin Stock (一般的な使用機器スピン ストック,Ippantekina Shiyō Kiki Supin Sutokku?)is the primary sidearm of the Pawn Soldier Troops. It is constructed upon a modified number 08 Spinner, which was originally the Pawn Spinner. It is a black square with a sharp blade on its upper part, which doubles for melee and ranged attacks. When it is unfolded, it can be placed on Sickle Mode or Rifle Mode. On its core part, there is a center with the shape of a sphere with the AstroNauter team symbol. Throughout its border are three buttons, which have different functions: The first button allows the Transformation (when pressed it starts numbering up to nine for the soldiers to transform when his number is announced). The second button allows a Finisher (when pressed for a long time). The third button allows Voyager Calling (again numbering according to the soldier's designation).
